If you are gonna cap Conq and Valor, and different specs have different stats....

Each week we do arenas and RBGs..we get capped...I love my shammy...but I cant possibly get full Male agility gear AND full Male intellect gear..Why not make it so when you wear your gear while changing spec that it changes with you?...Makes sense.....Just a thought make it work like this only with Epic gear (purple) ..I would imagine it would be worse in raiding...that you may raid for two weeks and lose rolls to others....ideas?
